A visual description of the labia minora resembling a thinly sliced piece of rare roast beef hanging like a drape. This resemblance is more pronounce on women whose labia minora overhangs her labia majora leaving the edges darker in tone to the pink or ruby color of the inner vagina.

"Hey baby, you mind if I taste me some of your roast beef curtain?"

"Maybe I could have a bit of your roast beef curtain while I wait for Mr. Viagra?"

The luscious protruding inner lips of a woman's vagina which is men’s favorite part to suck on during oral sex.
These inner lips are particularly sensitive and touching them makes the woman orgasm.
The inner lips of some genetically blessed women grow larger during puberty.
The inner labia of the majority of women more or less protrude beyond the outer labia but since the protruding lips are considered too sexy (too graphic) for soft porn, the guidelines mandate digital removal of these parts before getting them published. So virgin guys who are used to jerking off to porn pussies are not aware of this trait of real-life pussies.
